The Lowdown
Alright, Rusty here. Let’s run through what’s happening at Jaconé.
We’ve got a solid stretch of surf coming, but it’s not all smooth sailing. The real standout sessions are at the end of this week and the start of next week, but there are some big, heavy swells that are only for the experts.
Water temp is about 73°, which is normal for this time of year, so nothing to worry about.
First up, Sunday afternoon the 23rd of August. You’ve got a 6ft swell from the SSW, but it’s cross-offshore and a bit messy. The energy is moderate (613). It’s just a warm-up.
Monday the 24th is when things get real. Morning brings an 8ft S swell with a 13-second period, that’s proper groundswell, and the energy jumps (2077). It’s big, but the wind is still cross-off. By Monday afternoon, it’s a solid 10ft from the S with a 14-second period, and the energy is huge (3200). That’s a beast of a wave, clean, but only for the experts. Beginners, stay on the beach.
Tuesday the 25th keeps the size at 8ft, but the wind picks up, making it less appealing. The real gem in this first week is Thursday morning the 27th of August. You’ve got a 8ft S swell at 14 seconds, but the wind is offshore from the NE, a gentle breeze making it super clean. The energy is strong (2198). That’s the best of the first week, no question. It’s still a big wave, but the conditions are excellent.
Then we get a nice breather on Friday the 28th. The swell drops to 4ft from the S, and the wind goes completely glassy in the morning. The energy is moderate (689). That’s a fun, clean wave for the intermediates.
After that, the swell builds again. The 30th and 31st of August have some fun, glassy mornings with 7ft and 7ft ENE swells, but the period is shorter (8-9 seconds), so it’s a bit more local. The energy is still strong (906 on the 30th).
There’s a lull and a wind shift at the start of September, with a couple of days of poor conditions on the 1st and 2nd. That’s a gap you’ll want to sit out.
But then, the second week brings another standout. Thursday the 3rd of September morning is looking *really* good. You’ve got a 8ft SSW swell with a 12-second period, the energy is very strong (1503), and the wind is glassy. That’s a clean, powerful, long-period groundswell. It’s a big wave, but for the experienced surfer, that’s a session to remember. Friday the 4th follows with clean 7ft S swells.
The final shout-out is Sunday the 6th of September. A 7ft SSE swell with zero wind, completely glassy. The energy is moderate (720). A nice, clean way to finish the forecast.
If I had to pick the absolute best, it’s Thursday morning the 27th of August for the offshore winds, and Thursday morning the 3rd of September for the glassy, powerful groundswell. Those are the ones to circle on the calendar. Just remember, crowds can be a thing at Jaconé, so get out there early.
This is Rusty, signing off.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
